Venous Thromboembolism Chemoprophylaxis Compliance in the Surgical Intensive Care Unit.

Early initiation of venous thromboembolism chemoprophylaxis (VTEp) decreases VTE risk in trauma patients in the Surgical Intensive Care Unit (SICU). The frequency and variation of VTEp interruption by different surgical subspecialties in the SICU is incompletely described in the literature. The objective of this study was to examine VTEp compliance in the SICU in terms of uninterrupted VTEp following initiation, both by surgical service and time of year, to identify opportunities for improvement.This single-center quality improvement (QI) study examined all SICU patients, which are almost exclusively trauma patients, at our institution (1/2021-04/2022). Exclusions were therapeutic anticoagulation. Type of VTEp, calendar month of SICU stay, perceived indications for interruption, and primary service were collected.Of 5 434 patient days (PD), VTEp was not administered in 1879 (35%). Common reasons for VTEp interruption were ongoing bleeding (n = 964 PD, 51%) and periprocedural status (n = 651 PD, 35%). Periprocedural interruption was highest in July. Acute Care Surgery (ACS) (n = 208 PD, 32%) and Orthopedics (n = 188 PD, 29%) interrupted VTEp most often. ACS most commonly withheld VTEp for second look laparotomies while Orthopedics withheld VTEp for intramedullary nailing or external fixator application.Missed VTEp doses occurred most frequently at the beginning of the residency year, with a high percentage held for periprocedural status. Because the necessity of periprocedural VTEp holds is unclear, the appropriateness of these holds and any impact on VTE rates will be assessed as the next steps. In the interim, our findings provide targets for multidisciplinary QI endeavors.
